Just installed my vapor computer with dash kit, looks terrific and totally modernizes the bike (other than the suspension, frame, and engine). Anyways, for the retarded question of the day, I'm configuring the tach - how many pulses per revolution should I set - 1,2, or 0.5? 0.5, because the motor revolves twice for every one spark (hence 4-stroke)? Am I right? Brain no worky today.
